The Lowdown

Alright, let’s get into it. The early part of this run is pretty ordinary, but things start to build from Friday the 21st and really fire up around the 24th and 25th. There’s a solid gap of low-quality surf at the start, so don’t expect much before then.

Right now, Wednesday the 19th and Thursday the 20th are flat and weak. Jaconé is seeing small waist-high easterly swell around 2ft to 3ft, with short 7-second periods and very weak energy (63 to 166). The northeast and east winds are offshore or cross-off, so it’s clean, but it’s barely surfable. Water temp is 72°F, which is about normal for this time of year.

The first real standout comes Friday morning, August 21st. Swell jumps to 6ft from the ENE, period stretches to 8 seconds, and combined energy jumps to 541 (moderate). The wind is light NNE, cross-off, and conditions are clean. This is the best early session—good wave height, clean lines, and the direction is close to the optimum SE swell direction. It’s not huge, but it’s well-shaped for Jaconé’s exposed setup. Crowds are possible here, so get in early.

Friday afternoon and Saturday are a write-off—onshore winds and poor conditions. Sunday morning the 23rd brings a glassy, clean window with 5ft SSW swell, 9-second period, and moderate energy (325). It’s rideable but not a standout.

Now we get to the real meat. Monday afternoon, August 24th, the swell picks up to 8ft from the south, period 12 seconds, and energy is strong at 2330. Winds are light cross-off from the SE. This is big, powerful, clean surf—only for experienced surfers. Good shape, but it’s pushing into the expert zone.

Tuesday morning, August 25th, is the absolute pick of the whole run. Solid 8ft south swell, 14-second period, and energy is very strong at 2613. Offshore ENE wind at 12 mph keeps it clean and lined up. This is proper groundswell—long period, heaps of energy, and offshore wind. At this size, it’s definitely for experienced surfers only. The long period means sets will be bigger and more spaced out, making it easier to paddle out between them. The S direction is ideal for Jaconé’s exposure.

Wednesday the 26th still holds good waves—5ft south swell, 12-second period, offshore winds in the morning, energy at 788. Clean and very surfable. Thursday morning the 27th also offers 5ft ENE swell, 8-second period, but it’s shorter period and not as clean.

From Friday the 28th onward, the surf fades fast. Small, weak, and mostly poor conditions through to the end of the month. There’s a brief uptick on Monday, August 31st, with a glassy morning and 3ft south swell, 11-second period, energy at 307—decent if you’re desperate. Then by Thursday, September 3rd, another big swell arrives: 8ft SSW, 14-second period, energy 1941, but with light rain and onshore winds in the morning. The afternoon is glassy with 7ft SSW swell and 13-second period, energy 2262, and it’s clean again—another expert-only session.

So, the clear standout is Tuesday, August 25th morning. If you can handle the size, that’s the one to go for. The Monday afternoon before and the Thursday afternoon after are also worth a look for strong surfers. The rest is mostly small, weak, or blown out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
